Application filed March 26, 1920. Serial No. 369,139.

To all whom it may concern:

Be it known that we, l WILLIAM E. STROM- BERG and EDWARD H. SonMIoKINe, citizens of the United States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Print-Washing Machines, of which the following is a specification.

This invention relates to photographic print washing machines of the type which includes a washing liquid holding tank and a print holding drum rotatably mounted within the tank and formed of wire netting, or other reticulated fabric to permit the washing liquid to enter the drum and engage the prints placed therein, and an object of the invention is to so mount the drum, within the tank, that it can be conveniently moved to a position exterior of the latter, to admit of the removal of the washed prints without necessitating theimniersion of the operators hands in the wash ing liquid.

Other objects will appear and be better understood from that embodiment of our invention of which the following is a specification, reference being had to the accompanying drawings forming part thereof, in which,

Figure 1 is a washer. I

Figure 2 is an end elevation thereof.

Figure 3 is an enlarged end elevation of the washer, showing the drum in raised position and parts shown broken away for the sake of clearness. I

Figure 4 is a fragmentary detail sectional view of a portion of one end of the drumand the tank, with parts omitted for the sake of clearness.

Referring to the drawings the numeral 1 perspective view of the designates an elongated tank having a rounded bottom 2 and having the top 3 thereof open. The tank 1 is mounted on feet 4 which are located, respectively, at the opposite ends of the tank. Mounted for rotation within the tank 1 is a hollow elongated drum 5, having a portion thereof ex tending through the top 3 of the tank. This drum 5 is formed of wire netting, or other reticulated fabric, as shown more particularly in Figure 4. Water wheels 6, are mounted, respectively, on the opposite ends of the drum and are of diameters exceeding the diameter of the drum. A pair of normally angularly disposed bars or levers 8 and 9 is located at the outer side of each Water wheelG, and the levers of each pair have their meeting ends pivotally connected by a trunnion 10, carried by the adjacent water wheel 6. The upper ends of the levers 8 of thepairs of levers are connected by pipe sectlons 11 and 12, which form a water supply pipe, the sections being connected to each other by means of a T joint 13, for establishing communication between the water supply pipe and a suitable source of water openings in the pipe sections 11 and 12 and overflows the adjacent pockets in the water wheels 6, the wheels will be rotated, and since the latter are attachedto the drum 5 the drum will be rotated in the tank 1.

It will of course be understood that the rotary velocity of the drum will be regulated by the force and volume of water discharged through the openings in the pipe sections 11 and 12. During rotation of the wheels 6, the water in the pockets thereof will be discharged into the tank 1 so that a supply of clean water will continuously flow into the tank during the print washing operation.

Access to the interior of the drum 5 is had through an opening in the peripheral wall of the drum and such opening is normally closed by the door 15. Both the opening and door extend the entire width of the drum so that relatively large prints can be placed into and removed from the drum.

The connected ends of the respective pairs of levers 8 and 9 normally rest on brackets 16, secured to the inner sides of the end walls of the tank 1. These brackets are located at such points as to hold the drum 5 and wheels 6 properly spaced from the bottom wall of the tank 1 to permit of the free rotation of the drum 5 and wheels 6. The outer ends of the levers 9 are pivoted to uprights 17 mounted on the end walls of the tank 1 and are terminally pivoted in the bifurcated ends of handles 18. The handies 18 are adapted to have an upwardly a position above swinging movement in the levers 9, the downward movement of the handles being limited by stops 19 which engage beneath the terminals of the levers 9. When it is desired to withdraw the drum 5 from the tank 1, downward pressure is exerted on the handles 10 effecting upward movement of the lovers 8 and 9 away vtrom the brackets 16 resulting in the drum 5 being raised to the dotted line position shown in Figure 8. The drum may be held in this position means of pawls 20, carried by the handles 18 and adapted to engage in notches 21 formed in vertical bars 22, mounted on the end walls of the tank 1. The door 15 may then be opened and "the washed prints removed from the interior of the drum. It the tank 1 happens to be ti led with water and it is desired to raise the drum above the tank furtherdepression of the handles 18 to the full line position shown in- Figure 3 will effect raising of the drum to the full line positionshown in said Figure 3 or to the tank and the water level. The pawls 20 can then be engaged in notches 23, in the bars A? to lock the drum against downward movement. The upper ends of the leversS are connected to the end walls of the tank 1, by means of bars 2a which have pivotal connection with the levers 8*and the end walls of the tank 1 by means of pins 25. When the drum 5 is disposedwithin the tank 1 these bars 24 assume an inclined position. During movement of the drum from the tank 1, the bars 24 move to a vertical or substantially perpendicular position as shown in Figure 3 and form support-stor the upper or outer ends of the levers 8. During the upward movement of the bars 2 1 the bars will effect downward movement of the outer or upper ends of the levers 8 and result in the water supply pipe being moved to a position where it will not obstruct the openingof the door 15 in the drum 5.

In use, the tank 1 is filled, or partly filled with water. This can be caused either by admitting water under a high velocity through the openings in the pipe sections 11 and 12, or by any other means. The drum can then be either rotated in the tank to present the door to a position where it can be opened, or the drum can be raised out of the tank to either of the positions shown in Figure 3 which will permit the door being more conveniently opened. The prints then placed within the drum and the drum is returned within the tank it the prints were placed therein while the drum was in raised position. \Vater is then permitted to flow through the openings in the supply pipe so as to effect rotation of the wheels 6 and the drum 5. The water in the tank will enter the drum and engage the prints and during rotation of the drum will had to the interior effect a thorough washing of the prints. When it is desired to remove the washed prints from the drum 5, the flow of water through the supply pipe is discontinued and the drum raised to either the dotted or the full line position shown in Figure 3 and the door 15 is opened. to permit access being of the drum to the prints. It will be noted, by referring to Figure 1 that the onus of the drum 5 are spaced from the sides of the adjacentwater wheels to provide compartments 25 into which a portion of the water will enter through the end walls oi the drum 5. During raising of the drum the water in the compartments will return to the interior of the drum and during its passage will serve to release any prints that may adhere to the end walls of the drum. The end walls or" the tank are provided with overflow openings 26. If desired a suitable tray 27, shown in Figure 1 may be placed beneath the tank 1 for catching the overflow from the tank. In this instance the tray is shown provided with a discharge spout 28 adapted to be communicated with any suitable drain so as to permit of the.escape of any water in the tray.

One end of the tank 1 is provided with a vertical passage 29, the lower end of which communicates with the interior of the tank through an opening 30 formed in the lower end of the said end wall. Thus the chemicals washed from the prints and which gravitate to the bottom of thetank can enter the passage 29, thereby preventing accumulation of sediment in the bottom of the tank.

Having thus described our invention, what we claim as new is 1. A photographic print washer including a tank, a drum removably positioned within the tank, water wheels carried by the drum, a water supply pipe overlying the drum and the wheels and pivotally connected bars carried by the drum and tank for supporting the water supply pipe.

2. A photographic print washer including a tank, a drum removably positioned within the tank and a pair of pivotally connected levers associated with the drum and adapted when moved in one direction to effect a removal ofthe drum from the tank.
